packets.obj : error LNK2005: "int mainid" (?mainid@@3HA) already defined in main.obj
packets.obj : error LNK2005: "unsigned char * recvmsg" (?recvmsg@@3PAEA) already defined in main.obj
packets.obj : error LNK2005: "struct players * player" (?player@@3PAUplayers@@A) already defined in main.obj
Debug/Server.exe : fatal error LNK1169: one or more multiply defined symbols found

Server.exe - 4 error(s), 0 warning(s)

would anyone know how the hell I can fix this?

My guess is that you are defining those things in a header file rather than declaring them, so each .cpp file has its own copy of the data.

A header file should only declare data like:

extern int xyz;

A single source file in your project should declare that data like:

int xyz;

If this is not your problem, post all 4 of your files and I'll take a closer look.

Grrrrrrr I'm going to learn more with linked lists and rewrite the whole danm thing getting tired of that error, and yes I tried to delcare them as extern and still the same danm error

Post your code. Don't change things just because you get an error you don't understand. Learn why you are getting the error. Learnm what the error means. It will save you lots of trouble in the future.

If you 'd prefer to send me the code outside of this chat, we can talk over email or ICQ.

What I really need is a nicely done tutroial on how to make linked lists and their funcation. I really only made one linked list but it was not all that great.

Lol. I know they're bad, but it's better than trying to make one yourself.

Linked lists are tiny and easy to code. It's better to learn them than to always rely on some wrapper. That way if you are having a problem you can debug with intelligence. People that rely on classes to do all their work for them grow up to write crappy code.

yes I agree I'm not too much with using wrappers since they are really just others work. Like UDP Sockets I'm making my own while others suggest me to use wrappers and stuff. But I really need to learn linked lists so I have to try something to help me that is ez to understand.
